OPERATION
GENERAL CUTTING
See Figure 7, page 14.
Rest the front of the saw base on the workpiece and align
cutting edge of the blade with the line on the workpiece.
Make sure the power cord is out of your way and not in the
line of cut. Start your saw and move it forward on the work
surface. Apply downward pressure to keep the saw steady
and only enough forward pressure to keep the blade cut-
ting.
CAUTION:
Do not force the saw
overheat the motor and break saw blades. Use
clamps or another practical way to secure and
support the workpiece to a stable platform.
ORBITAL ADJUSTMENT kNOB
See Figure 8, page 14.
The blade of the saw cuts in an orbital motion. This feature
is adjustable and provides faster, more efficient cutting. With
orbital motion, the blade cuts through your work in the up-
stroke but does not drag across your work in the downstroke.
The "0" setting should be used when cutting materials with
more resistance. The higher settings (3, 4) should be used
when fast cutting in soft material is desired.
INSTALLING JIG SAW BLADES
See Figure 9, page 14.
 Unplug the saw.
 Remove the chip shield if needed.
 Lift the rapid change blade clamp until it stops.
 Holding the rapid change blade clamp up, insert the saw
blade as far as possible into the slot in the saw bar.
 Check to make sure the back of the saw blade is centered
in the groove of the roller guide.
 Release the rapid change blade clamp. Make sure the
blade is securely in place.
 Replace the chip shield if needed.
REMOVING JIG SAW BLADES
See Figure 9, page 14.
 Unplug the saw.
 Remove the chip shield if needed.
 Lift the rapid change blade clamp until it stops.
 Holding the rapid change blade clamp up, remove the
saw blade.
NOTE: The jig saw is designed to use T-shank blades
only.
STRAIGHT CUTTING
See Figure 10, page 14.
A straight cut can be made by clamping a piece of wood or
straightedge to the workpiece and guiding the edge of the
saw against it. Make the cut from one direction only. Don't
.
Forcing the saw may
cut halfway and complete the cut from the opposite end.
SCROLL CUTTING
See Figure 11, page 14.
Scroll cuts can be made with the saw by guiding the direc-
tion of the cut with applied pressure on the handle as shown
in figure 11.
CAUTION:
Excessive side pressure to the blade could result
in broken blades or damage to the material being
cut.
BEVEL CUTTING
See Figures 12 - 13, page 14.
Bevel cutting angles may be adjusted from 0° to 45° right
or left. Angles for cuts from 0° to 45° in 15° increments are
marked on a scale on both the left and right side of the base.
Lines are also drawn from the middle section to the back of
the base for accurate alignment.
An arrow under the motor assembly provides an indicator at
each of the 15° increments. A protractor is recommended
for making accurate cuts.
 Unlock the base by moving the base locking lever forward
and sliding the base forward from the locking pin.
 Select the desired angle on the base.
 Once the desired angle is reached, slide the base back-
ward to the locking pin and tighten the base locking
lever by moving the base locking lever under the motor
assembly.
PLUNGE CUTTING
See Figure 14, page 15.
WARNING:
To avoid loss of control, broken blades, or
damage to the material being cut, always use
extreme caution when making plunge cuts. It is
not recommended to plunge cut materials other
than wood.
 Mark the line of cut clearly on the workpiece.
 Set the orbital adjustment knob to "0".
 Tilt the saw forward so that it rests on the front edge
of the base and blade will not come in contact with the
workpiece when the saw is turned on.
 Make sure the blade is inside the area to be cut.
 Using high speed, start the saw and slowly lower the
blade into the workpiece until the blade cuts through the
wood.
 Continue lowering the blade into the workpiece until the
base rests flat on the work surface, then move the saw
forward to complete the opening.
 Use only the 7 teeth per inch blade for this type of cut.
